With the exception of propane, Vermont consumers are paying less today for gasoline and other fuels than they were a year ago.

Regular gas is 15 cents a gallon cheaper this month than a year ago, averaging $3.596 a gallon, according to the state’s monthly fuel price report. The price, however, has crept up 3 cents a gallon since May.

At $3.565, home heating oil is 12 cents a gallon less than it was a in June of last year. Over the last month, the price has dipped 4.7 cents a gallon.

Kerosene and diesel prices have also declined, the report said.

The June price for kerosene averaged $4.094 a gallon, the same as last month but slightly less than a year ago when the price was $4.108 a gallon.

Diesel prices averaged $3.947 this month, a drop of 14 cents a gallon from a year ago and 5.2 cents a gallon less than last month.

Propane, which is used for heating and cooking, averaged $3.024 a gallon this month, a slight increase from May, and 3 cents higher than June of last year.

According to VermontGasPrices.com, the best places to buy gas last week were in Rutland and southern Vermont. The Irving station on Grove Street had the cheapest gas at $3.42 a gallon. Five Rutland-area and seven Bennington-area stations were listed as having the best pump prices.

Most of the highest-priced gas is concentrated in the central and northern part of the state. The Shamrock station in Newport and the Shell station in Killington were tied for the most expensive gas at $3.69 a gallon.

According to the federal Energy Information Administration, gas prices nationwide will average $3.53 a gallon over the summer, through September.

For the year, the EIA is projecting an average price of $3.49 a gallon, a drop of 14 cents from 2012. The price is expected to decline further next year, averaging $3.37 a gallon.

Heating oil prices are also projected to fall next year to an average of $3.62 a gallon, 14 cents lower than this year.

However, the EIA adds this disclaimer: “Energy price forecasts are highly uncertain, and the current values of futures and options contracts suggest that prices could differ significantly from the projected levels.”
